no fire
From past experience, disconnect the "P" leads at the mags, then try the start.
A friend had the same problem first start, he swore he had pinned the ignition switch out correctly. He pinned the switch out again with help from others and it seemed fine, I asked him to just disconnect the leads but after pinning them out again decided to have them rebuilt, the engine was mid time off of another RV, but the mags had not been touched. When he got the mags back he put them on and it wouldn't start again, I again asked him to humor me and remove the "P" leads from the mags. He did and it lit in 2 blades. He did have the switch wired correctly, but when he put the leads on the mags the shielding would ground out, so when he pinned them out off of the mags they would pin out correctly then ground out when they were put back on the mag. I'm sure it's something simple. Make sure that the mixture goes to full ICO, before you do this. Rt |

P-Lead Adaptors?
In 2013 I decided to replace my homemade P-leads with Bogerts. One of the pair wasn't long enough and caused the mag to short out. Just a possibility...

On my first start attempt, the engine would occasionally fire but not start. I checked and cranked at intervals until the battery was getting weak. No start.
When I was climbing out of the aircraft, I noticed the mixture lever in the idle cutoff position. Idiot! I put the battery on charge and went to lunch. Next try it fired up on the second blade... Of course all my helpers who had come to hold fire extinguishers and see the engine run had great fun at my expense... |
First engine start
Dave,
Probably a silly question but did you perhaps look up the lower intake and see if there is a plug just above the throttle body/carb? Engine manufacturers and rebuilders sometimes put a rubber cap in the lower opening at the throttle body to keep debris & foreign matter out during shipping. Might be worth a look, sounds like the appropriate symptoms if everything else checks OK. That would definitely prevent a start since there is no air going into the engine, (fuel, air & spark req'd). I had my 1991 engine recently rebuilt by Poplar Grove Engine rebuilder up in Chicago. While installing it we did a thorough inspection and found a red rubber plug right at the bottom of the engine intake at the throttle body attachment so it was fairly easy to pull it out. And no, they said nothing about it so I assumed it might be standard procedure. It would have definitely prevented a start. Except for that remission of information they did a superb job and the engine has been running flawlessly. Hope this is your start problem because it would be a super easy fix. Good luck! |
Confirm, plug wire firing order?
