I made it out to the airport today, = soldered up the=20 CAS and installed it. Before I cranked it over, I put it in mode 8 = and=20 fired it off. The usual nice blue sparks. Then set it to = mode 0 and=20 cranked with the plugs out and pumps/inj off. No spark. = Cranked and=20 looked again. Every so often there would be a weak spark or 3, but = most of=20 the time, nothing. So little or no spark. I measured the gap = between=20 the CAS and the wheel and I get between .045 and .050 (I don't = have the=20 right feeler gauges). This contrasts with Mark having to move his = CAS to=20 .020 to make it work. The flange that the CAS sets on is = part of the=20 cast casing and is machined flat where the CAS is bolted in. It = looks like=20 this sould be the correct setting and would never have concidered this = to be the=20 problem (still don't know for sure if it is) if Mark hadn't mentioned = it. =20 Have any of you Renesis people run into this? Some possibilities = are that=20 it needs a smaller gap for the EC-2. or that this being a "grey market" = engine,=20 they let the builder figure it out the spacing. It could be = something=20 else, but my plan is to grind the flange down to a gap of .020 and try = it. =20 It will be a bitch to get to. I can add spacers if I need to move = it back=20 out. Anyone else have any suggestions as what else might be the = problem?=20 Bill, Tracy and Dennis, did you have this problem with = spacing on the=20 Renesis, or did you just install the stock CAS and go? I = checked=20 the factory Manual on CD and they have no specs on the gap. BTW no = RPM=20 display at these low cranking speeds. Lynn, I am running a stock = 13b=20 autotrans starter. It cranks well, until the battery runs = down. Yes,=20 I have my 12 lb Catto prop installed. I put a little oil into the = plugs=20 holes before cranking.

Dennis, I'll put that inverted drain = valve at the=20 top of the radiator housing this weekend. I also have 2 air purge = lines,=20 one running from the rear top of the engine and the other from the = radiator,=20 radiator cap, both going up to the surge tank to purge air out = of the=20 system. Bob, I think your harnesses are fine! Picked up some = Marvel MM oil for squirting into the plug holes. Bill, I have = been=20 cleaning my plugs with carb cleaner, then blowing them dry. If = that=20 doesn't work, I'll use the rice hulls. I will attempt to fire it off = once the=20 urathane sets and I get the flange cut down. Guys, thanks for all = the=20 suggestions! I'll keep you posted.
