30+ pulls to cold start Redmax 7500! Anyone else have this problem?

Like the title says, I have 2 7500 blowers. One is used more than the other. The most used one can take between 30-50 pulls before it fires for the first start of the day. Summer cold starts in the morning require around 15 pulls and currently at 35 degrees in the morning it takes closer to the 50 pulls. Once it warms up it will start with one pull. Air filter is new and so is plug. Primed 5-7 pumps and choke is on. Carb problem? Thanks in advance for any help.

I only choke both the 580 and 570. No priming of the bulb but the 580's get used all the time. Unless they sit I never prime them. No matter how cold it takes 3-4 pulls on first start up. I always have throttle set halfway.

I don't know what Redmax's manual says to do for cold starts. But our guys will bring any unit (we only use Tanaka) back to me if it dosen't start
with in 10 pulls. This is the way I showed our guys to start them. Prime it untill you see fuel going back in to the tank in the return line, full choke
and Full throttle. Most of the time they will start on the first or second pull, some times 3 or more if it's a older unit.

If you do it this way and you still have to pull it alot, then you have a problem some where......

If ANY machine doesn't pop-spit or sputter with-in 4-5 pulls it's time to quit and find out why, Not continue pull'n...... All your do'n is wearing your arm and recoil assembly out.....

Breezmister hit the nail on the head. Half throttle or above first cold start of day, will fire within 3 pulls, if you leave it at idle, you'll yank your arm off.

Clean carb. No way should they be that hard to start.

Had 2 8500's with the exact same issue. Replaced all kinds of parts with no improvement. They were like this from day 1.
