<p>Hi Carl,</p>
<p>I live in the Midwest, just eat of Indianapolis. I have an MA3-SPA with an accelerator pump. Generally on a cold start I only pump it a couple times, and it will usually fire right up. Once in a while it may fire up and quit, just give it a couple more pumps, and it usually keeps running from then on. As Christopher stated, never pump for a hot start. Good luck,</p>

<p>Arnie, I've ridden in, but never piloted, several aircraft with no primers. As Christopher noted, here in DFW I've just never even thought about having one!</p>

<p>Christopher, I have the MA-3SPA carb, but it does have the accelerator pump. I tested that before I installed the carb; mostly when I just wanted to put some 100LL in the fuel bowl to keep things wet. I just wasn't sure how many pumps of the throttle should be…</p>

<p>Christopher, I have the MA-3SPA carb, but it does have the accelerator pump. I tested that before I installed the carb; mostly when I just wanted to put some 100LL in the fuel bowl to keep things wet. I just wasn't sure how many pumps of the throttle should be enough. I didn't really count, but know for a fact it was more than 4! Even tried pumping it a time or two while cranking. Runs great once running; no stumbles or hesitation when advancing the throttle. Just that initial start. Well, the only start! Did not try and restart once I shut it down. In retrospect, I should have, because I had forgotten to turn on the alternator field so was not seeing a charge.</p> if you got the ma-4 standard…tag:zenith.aero,2022-03-28:2606393:Comment:8649092022-03-28T13:43:34.767Zchristopher fryatthttps://zenith.aero/profile/christopherfryatt
<p>if you got the ma-4 standard carb. on O-200 it will have an accelerator pump, pump the crap on cold days, for me 4-5, and never before hot restart. I leave throttle sightly cracked during strart ready to pump a bit more fuel if needed. </p>
<p> based on your locale it shouldn't need a primer, use one port in manifold for carb air temp id suggest as carb ice might be in your future! down load a copy of O-200 owners manual I posted here before for good operating tips…</p>
