Choke Pulloff - Marine Carb just rebuilt

<< < (2/5) > >>

5stareventsdj:
Will do. Thank you Cliff. I am going to also check the release time on the choke pulloff, but I think the stop is my big problem. :-)

Cliff Ruggles:
Typically doesn't have to be really quick on a Marine unit, 2 seconds or so should be fine......Cliff

5stareventsdj:
It appears that my set up doesn't have a secondary lockup. Does this appear to be correct?

Not sure how pics work in this but I attached one.

Thanks!!

greg this might sound stupid. but have you (with the engine off ) put the throttle in wide open and looked past the sec. air flap to see if the lower plates are opening up to full position? it sounds like you have a linkage problem  ( ether the throttle cable or the mechanical linkage between the primaries and secondaries needs to adjusted ) and your only running on the primaries. ive never worked on a marine carb but from the picture you dont have any lockout on the secondaries. jmtc. dean

5stareventsdj:
Thanks for the reply. I've been reading alot about the secondary lockout looking at pics, videos and Cliff's book. I was ready to disable mine until I looked at it to see that I don't have the lockout that I have heard so much about.

I have looked inside to see that the secondary throttle is opening. with the air cleaner (spark arrester) off, I haven't seen the air plates open on the secondary side. I have only checked out of the water though and am not able to give full throttle with cooling from my garden hose.

I hope to get on the water to confirm. MY WOT problem is driving me crazy. I can't tell you how much time & effort I've spent on this.

Greg
