wrong firing order

[AlanH]

Been trying to set up my carbs with a colortune and accidentally put 3 and 4 the wrong way round. I realised it straight away.

Would this cause any problems?

The engine has seemed a bit lumpy since but that could be my setting up.

Doubt it, try getting the cam 180 degrees out, that's much more fun!

I would put the leads back to the cilinders where they belong. The lumpyness will also dissappear then.

I've tried doing the carbs with colourtune without much success.

Steve showed me how much easier it is to start from scratch by setting the bridge heights and doing both at the same time, and then listening with a length of hose.

15 mins later, better setup than 5 days faffing about.

Ps, don't forget to check/set ignition timing.

Oh cr*p

I replaced the real oil seal in the engine and it's leaking like Niagra falls.

Seems to be one problem after another, I never had much problem with the OHV engines (although replacing an oil seal is a fairly standard) job.

I really don't think that 1850s are for me.

Annoying when cars resist your best efforts to fix them I must agree, just a thought though, what is the condition of the sump gasket at the back there? I replaced my oil seal but still had a leak which was the sump not mating well on the rear oil seal housing in the end.

what is the condition of the sump gasket

Good point. I replaced the sump gasket so I suppose It's just as likely that I cocked that up.

I will check.

Sorry to say you probably have one of those new crank seals with inadequate spring tension.
Do you still have you old seal? Compare the spring tension and length and you will see what I mean.

You can reuse the spring from your old seal, or shorten the new one accordingly, or find a NOS seal from somebody good and who
knows the importance of replacement part quality....

Lot of possible here, the sump pan sometimes becomes distorted if the sump bolts are done up to tight so that when a new gasket is fitted it actually holds the mating face off the gasket!
Cure is to put a flat piece of metal in a vice that fits between the sump lip and the sump pan and flatten it with a hammer to make the sump face flat again.
If the rear seal is gone it with come out of the bell housing.
These engines are getting old now and some have been "got at" by unskilled mechanics.
Good luck.
