Cold Start difficult

[leeroy_25]

Hi Guy\'s I have noticed in the cold weather the last week or so my rx7 is very hard to start. it tuns over a lot. if I give it a bit of throttle it goes eventually and once runnning is fine.. However I am a bit worried about flooding it while trying to start it.. Is there some adjustment on the throttle body for cold start? I have  aleaking LIM gasket I know which also makes hot start a bit temperamental but in normal ambient conditions it starts fine.

Can someone give me some advice on whether I should start it with lots of gas a bit of gas or if there is some adjustments I can make to help?

Thank you
Lee

This is what im partly finding, im guessing it might be the battery, as its cold it gives less power 2 the starter motor, my battery is fairly new, but I would guess with an older battery it might find it harder, make sure u turn off all extra accessories such as the blower? Just a thought.

I have not long got a new battery and it seems to tunr over okay.. I don\'t normally have anything else on either?? With a rotary cold should do it a favor as everything should be nice and tight!!

run a warmer leading plug.  assuming you are running 9\'s all round change to leading 7\'s....as long as you are running a fairly standard lump...

Thank you i\'ll give that a whirl! I stil have the old boxes so I can see what\'s gone in.. but they were all the same I know that much. Which is classed as leading.. I have never been sure on that. Top or bottom?  Will that help warm start as well as cold start??
At the moment I am on a stock motor but looking to run a single turbo set-up with my stock ports some additional injectors a Power FC ECU and go for around 400bhp. wil the 7\'s still be okay? I gather that\'s not asking too much of the rotary to get that power!

Cheers

Hi mate, had similar issue, went from 10.5\'s all round to 9\'s leading and its been spot on since

the leading plugs are the lower ones....but on a modded engine its probably best to run 9\'s and above...but hey your ok for now....

Cheers mate.. I\'ll try and get a pair of 7\'s for now.. I checked and mine are all 9\'s.. I guess the LIM gasket won\'t help much and I need to check the TPS voltages to make sure what they are.
