Turned out excess oil in the cylinders was 'oiling' the plugs, which looked the way you describe yours, yet I'd rebuilt the top end. In my case, it was the l/h crankshaft oil seal which was allowing air (but not oil, so no clues) to move in and out of the 'cases on the down-stroke of the pistons, thus defeating the rudimentary crankcase scavenge system which depends on crankcase pressurisation to expel oil into the timing case to be returned to the oil tank. Result being a crankcase contining more oil than it should, which was getting picked up by the crank and flung against the cylinder walls, overwhelming the rings and slowly oiling the plugs 'til they gave up (the plugs don't need to be 'whiskered', like an old two-stroke, to quit, a coating on the centre electrode will do the job). Dead easy to fix, dead hard to diagnose! Good Luck, Pete

Dont know a lot about Pans but thinking today, have Pans got solid lifters? If so valve clearances, if there not adjusted properly, can close up as the engine gets hot, you then lose compression. As it cools compression comes back. If hydraulic this wont happen of course ![]() Just a thought mate.

After a lot of time and effort....and not an inconsiderable amount of dosh.... He's on the road!! Stripped down and re-built tranny - old wet tranny bits still in there; Clutch, stripped and re-built, pressure plate was on the wrong way round; Carb stripped and re-built and re-tuned; Rear fender re-aligned; new points; oil drained, and re-filled; fuel tank raised on brackets (couldn't for the life of me work this one out, tank was correct replica and mounts appeared to be in the right place....); new leather tank 'bra' made; seat posts welded to frame; new plugs, battery and filter....and i think that's it. Anyway, took him out and he runs real sweet. Went to Thames Valley H-D and had the Hoggies drooling over a 'propper' Harley as one of them put it. Going back tomorrow for a dohnut!! ![]() Going to international and planning to go to next year's Super Rally in Greece; any other Pan/Shovel guys going? We can go in convoy and repair each other!! |

You either sold a pup to Roger who then sold it on to Che who then was grateful for you turning up so she could sell the shed on... or was it sorted when you sold it to Rog, and since then he and Che have slowly but carefully reverted it back to a shoddy mess... or is this typical of the never ending saga of trying to get a Pan running reliably in all departments? ![]()

I do have to thank Roger and Kim (Che) for keeping it on the road; as someone once said of classic vehicles, "we are just custodians", no doubt it will find it's way to someone else in due time. BTW, we will be sharing b'days next year - my 40th, it's 50th...that'l be a parteee! ![]() ![]() |
