Default Re: Ignition timing 1941 flathead

Thanks Terry and Ken,
I will look in tio the power valve. I did not take note of the #, and the kit came with two. One was a little different ( had a lower profile and not so pronounced plunger.) Also what float level is common? I set it at 1 1/4".
I will also have a peep at the main jets to see what they are as well.

The reason I think it may be a distributor problem or spark isue is that is seems to run like it is dropping a cyl or two when it is at driving rpm. I drove it yesterday and up to 35mph is good but over that she's a bit bumpy feeling. I did a choke test and it got worse so even though it feels lean to me it may be too rich and could be a power valve issue or main jet. Also it still has cloth covered plug wires. any concerns there? I guess I need to open the hood in the dark and see if I have any wires grounding.

Davy
