Questions for PMO carb users...
What are the cold start characteristics of the PMO carbs? Do you have to wait a while before you can drive? My CIS is driving me crazy with the cold start issue. I'm looking for some feedback from those of you with PMOs on a street machine. I know that CIS can be made to work really well, but I am curious of the alternatives. My car runs fairly rough until warm, then it runs great. Can the PMOs be set up to work better than CIS on a daily driver?
Thanks for the input.

Is your WUR working on your CIS? Mine runs a little rough for about a mile or two, but I'm also using a hand throttle. I just live with it until things warm up.
PMOs are quite an expensive outlay for CIS that runs a little rough for the first few miles...

Hey Steve,
My car always coughed for a few minutes till warm. John Walker tuned on it and now it starts cold and runs great right off the bat. I'd get Mayo or one of the others down there to see if they could tweek it out a bit. |

Maybe you might look into used Webers, or how about Zeniths? Solexes? I don't know...
Well working CIS has its advantages. I do know this: trying to find a working CIS system to replace an existing one has been an utter *****!

Kemo, fix your CIS cold start problems and save the money for something else.

I would think real hard about buying into old Webers over CIS to solve any issue on a everyday driver.
You could rebuild the CIS and have a no maintanance or start issues for pennys in comparison. The PMOs will give you some fun things but cold start isn't going to be one. Well, that is what I have been told anyway. I too had a miserable CIS until it was tuned properly. Now it is a real pleasure to work with. |

I have no cold weather problems with my PMO conversion. However, cold around here is 40 degrees.
