your CDI is WASTED!
I guess you didn't read the entire thread , that was the problem but now I am having trouble with an air leak !
Hi Marc...I apologize for crashing your thread with that childish saran wrap comment. It was my lame attempt at humor.
I've had many of these engines apart, and I'll help you get it back to normal.
There are 2 crank seals...one behind the small gear on the clutch side, and another behind the magnet on the magneto side.
Remove the clutch and magneto covers and look to see if either one of these seals appears to be standing out. They should be flush with the engine case, or slightly recessed. Use a flashlight so that there is no doubt.
Lame joke nothing,I used it twice today.HD
I think that the crank seals look fine and on close inspection I notice that the carb is leaking gas.
It wasn't before so i think that that gasket on the carb bowl blew out I am going to take it off clean it and make sure and rule the carb out first.
I changed my mind in the last phot it loks like the gasket is pushed out a little is this enough to cause a signifant problem?
Yes...The crank seals look perfect!
While you have the carb apart, be sure to check the float to make sure it doesn't have fuel in it.
take a good look at the last photo I think it is pushed out a little
From the photos...everything looks fine regarding the crank seals. If the seals fail, or push out, there will be a lot of oily residue. Both sides appear dry!
I guess it was lame ,sorry about that marc.HD
Well it's good news bad news, I still have to play case the vapor leak!
Ok sealed up the carb it does not appear to be running hot but..... after warming up and getting it to idle I had a loss of power and then it stalled before I could test for a vapor leaks (but it did not seem to be hot ie the plug boot was cool)
It could be one of two things either it's not getting enough gas or I still need to change the magneto. anyone have any advice,
I have a lot of patience and it is being tested
