I ordered a set of bearings for my very used generac belt-drive genhead last night, with spares. Total cost: $25 for two sets.
12/2 produces cleaner power, with an impulse every other stroke as opposed to one impulse in four strokes with the one-banger.
The Lister 12/2 and CE etc all produce 2 power pulses followed by two exhaust strokes, making the engine sound 'lopsided' when starting up. The cranks are at 180 degrees to each other. I don't know if the Indian engines have the same arrangement.

Bob, when I want to be I can be a FUCKING good engineer, but I fall so far short of even lesser gods like henry ricardo and james watt and otto diesel and a string of other names whose boots I am not fit to lick it ain't even funny, and THEY worshipped people like newton and cavendish and maxwell etc.
Procrustes, shame on you. It's my recollection that the 225/6 had sparkplugs
I hope that either route will be better and cheaper than a "big box" genset...
There has been mention of the great personalities of science and engineering. What made these people great is not raw intelligence or the willingness to look at things differently then what is commonly known, both are fairly common by themselves, but the combination is not, also need a good deal of luck.
interestingly i can find formulae for every facet of an engine, from volumetric efficiency to mach index's, from cylinder pressures to flame propagation and ignition timeing, connecting rod ratio's to chamber design, 1st, 2nd, 3rd, etc harmonics to resilient mounts, literally every part and parcel of an engine can and has been analized and expressed in some form of formulae, .... save one!
SIGH...PROCRUSTES, you just sadden me by the way you post, and then hide behind your hands (mouth?)
1)You said "I was only informing ListerDiesel". No, you were not; you said "Utterpower.com is behind the bronze idler." THAT is a lie. utterpower was not, and is not behind the bronze idlers. And you were told so. So you were NOT informing ListerDiesel, you were pumping them full of your brand of sh**.
2)If I was attacking you, you would know it.
You constantly post half-truths, innuendos, and outright bs. Most on this forum are kind souls, and don't even attempt to correct you. But is it kinder to let the dog snarl and worry at people's pant legs who are walking down the sidewalk, until one day someone has enough of it and shoots the dog, or is it kinder to correct the dog as needed, so he no longer snarls, etc?
3)Insofar as posting in caps goes; am so sorry for you. Have posted how it is with the idlers several times, and if you ever took the time to read and understand it, you would not keep re-posting the garbage you do. So I encourage with caps. If you don't like that, TOO BAD.
4) A recent post said "But I say the problem lies in the location in the idler bolt hole (or the location of the cam shaft)......Not the material used for the gear".
Now xyzer is a really decent sort of person, you can tell it by his posts. However, he did not need to say that at all, because no one else to my knowledge HAS RECENTLY SAID THAT IT IS THE GEAR MATERIAL THAT CAUSES THE PROBLEM.
Indeed, JohnF said "I think the main problem is that the hole for the idler gear is slightly off in some engines, causing backlash problems. No aftermarket idler is going to solve that and a hardened one is merely going to ensure that other parts that are much more difficult to fix, break."
And indeed, about that I posted "Thank you John, perfectly written, and absolutely true."
The truth is, The Indian Listeroids have cases whose crankshafts are not placed where they should be, their cams are not located where they should be, and their idler pinions are located wrong. Now GIVEN PART, OR SOME, OR ALL OF THOSE PROBLEMS MAY BE FOUND IN ANY ENGINE, AND THE INDIANS ARE NOT WILLING TO CORRECT IT, HOW DO YOU PROPOSE WE SOLVE THE PROBLEM IF IT IS PRESENT?
SORRY, the only fix that will work reasonably well for a reasonable price that I know of is the bronze idler.
A grade 25 CI cam gear, and grade 25 CI idler pinion, combined with the steel crank gear that all Listeroids use, to the best of my knowledge, INSURE a really bad "train wreck" when the engine centers are not within 3-7 thousandths of correct.
Grade 5 idlers and cam gears, such as Prakash, Ashwamegh, and others use, are so soft that they will erode rapidly , and have a very low life expectancy at best, EVEN IF THE ENGINE CENTERS ARE proper. Now please tell me what other solutions you propose??
Someone please tell me a simple, inexpensive solution.
PROCRUSTES, UTTERPOWER IS NOT "BEHIND" THE BRONZE IDLERS, GEORGE HAS ONLY REPORTED ON THEM. AND, he was part of the solution, not part of the problem. Why don't you report something factually for once, instead of BS?
Bronze would seem to be a strange choice for a gear, unless it is 'gunmetal' which is slightly different in composition. There are slight benefits in casting and machining, but for a straight-cut gear the tooth loadings would preclude a relatively soft metal. The only bronze straight-cut gears I can recall are the safety gears on my lathe which are there to protect the gear train if you have a jamming of the saddle when screwcutting etc.
I would have thought that the material costs alone would have mitigated against bronze/brass/gunmetal.
Would you please tell my wife " Buickanddeere was right"
