My roc starts fine when its cold but seems partially flooded when I start it when the engine is warmed up. I suspect leaky injectors. Do I by new after market ones, do I refurbish the old ones? If I should by new ones what kind work well? How big do I go.

Also please read my post 305 TPI won't run on a hot day... are these problems linked??

Appreciate the help!

I say with the prices on injectors, might as well replace them intead of spending 1/2 the cost just to clean them. So you will get nice clean used injectors.

They have to have some kind of 'life' to them. Imagine how many times they open and shut over 100,000 miles.... Just enough of a reason to replace.

 

Go and get some new ones. I went thru the same problem and it turned out I had a leaker. I just put in Accel 23# injectors and the problem is totally solved.
In your case I believe Accel makes 19# which is the what the stock pressure is on your 305.
The injectors are $229 US --alot cheaper than new factory ones.

That solves it, new ones are going in, thanx for the help.
