I use the club's DR300/180 for towing and the DR400/180 that I have a share in. Both hangared (in the same hangar). They don't have a primer. Both use 4 to 6 pumps on the throttle and start with the throttle closed then moved to open by a few mm, barely more than taking up the backlash. The DR300 starts on the key, the DR400 has a separate starter button and in that case I start on the left mag as briefed.
They usually start after a few compressions and if they don't I stop, pump a little more and try again. Each try is about 5 seconds, certainly not 30. Once it starts running I increase the throttle to get it running at 1100 to 1200 and try to remember to switch the DR400 to both mags.
Starting problems have been because of a tired battery or some impulse mag problem.
When warm one pump, throttle almost closed and start.
If it won't start I don't try too hard, it seems either to start fairly easily or not. After half a dozen tries I go and ask for help from the experts before I've flattened the battery. They tend to do the same as me, with the same not starting results.
